Water pouring onto the floorboard - pass side. A/C?

My passenger side floor board is flooded with water - especially when I make turns - it pours out. I took the fan off and it seems ok. I put an air hose up the pipe underneath the dash to see if I can see where the water is supposed to come out under the engine. But I couldn't. I am guessing it is plugged somewhere. Also, does the fan act like a pump? It looks like the water has to travel all different directions before it finally makes it's way out to the outside. Thanks for any help! Where does the water drain out under the engine. For the life of me, I can't find it.

There is a drain that is below the evaporator on the firewall. You can take a coat hanger and straighten it out to run it up the drain and clear the blockage. The drain either sticks out or looks like a rubber elbow.
